各位有用ubnt AP 嘅ching, 大家會用咩方法去mount 隻飛碟? 會將佢掛上牆/天花定隨便放佢就算?

又唔係有假天花/辦公室，隨便搵櫃頂擺算

---

作者: hellfighter    時間: 2017-7-28 13:37

屋企用既, 咪放高身既櫃頂囉.

作者: killerxp    時間: 2017-7-28 14:38



其實係唔係放高d好d？

    係. 但高D 只係指一般室內既高度, 而唔係幾層樓都中空果種.

作者: yankees    時間: 2017-7-28 14:43




    理論上係, 不過基於美觀條件我本人就放係電視櫃頂算數

點對點擺位方式 最好

Mine is hung high on the wall.

作者: killerxp    時間: 2017-7-28 16:57



明白，不過一般屋企如果之前無諗住裝係天花或牆，會有明線。

    所以屋企多數都係放係高身櫃既櫃頂就算數

裝修時做定個天蓋比佢

---

作者: C-Leung    時間: 2017-7-28 20:02

我想問，呢d ceiling mount ap放高位係咪都係面向下先會收到最好？
如果放櫃頂/假天花上，係咪應該上下反轉擺？

---

作者: alan4k    時間: 2017-7-28 20:08

我覺得最麻烦就係會發光或閃光，如果熄晒室內燈佢會光得滯；唔開光佢似隻膠碟痴咗係天花好礙眼。我係收埋入假天花。

搭單問下ubnt ap 個wifi 够唔够勁？
我而家用緊 liNksys 8500 做 AP, 穿一間房(两塊牆)就收吾到乜制
想換 ubnt 試下，但最怕衰過而家

所以想請教一下

thx

    Signal strength of commercial grade indoor APs is usually weaker than their consumer grade counterparts because the former is designed for multi-AP deployment. You probably won't gain much by switching to commercial grade AP if signal strength of your currently wifi router is not strong enough.

    呢層未必. home use product 一向唔會咁大power.
2. 擺放位置. 呢類enterprise AP, 通常放係天花 同通道位. 接收能力佳. 3. 特別供電for AP only. 相對穗定.

幾項因素加埋都會令到. 用佢用enterprise AP 接力"能力" 好過家用router.

one on one 可能分別不大. 但當你單位佈局已經要有兩隻時. 用兩者家用. 可以不及用2 隻enterprise AP

---

作者: alanh999    時間: 2017-7-30 18:32




    Yes that's why I mentioned that commercial grade APs are designed for multi-AP deployment.

---

作者: 556556bt    時間: 2017-7-30 19:46




    " designed for multi-AP deployment" doesn't mean it's not good in single node deployment

    As said before, usually wifi signal strength of commercial grade indoor APs is weaker than commercial grade APs/wifi routers.

#15 is asking if an Ubnt AP has stronger signal strength than EA8500 which is a high-end model from Linksys so he could establish stable wifi connections 2 walls away from where the AP is located. I therefore suggested that replacing the Linksys wifi with an Ubnt AP won't help him overcome his problem.

If #15 is willing to deploy an ADDITIONAL AP in where wifi signal of the EA8500 is incapable to reach then this is a solution.

作者: 556556bt    時間: 2017-7-30 20:02




    u may refer signal strength to the radio power which is probably low for the standalone AP product. however, due to its specialty and design, it will perform better than home wifi router even with lower radio power.

You know, it is meaningless to count only on the power strength for the overall reception of wifi connection.

Per my experience I don't think an Ubnt indoor AP will do any better than an EA8500 2 solid walls away.

---

作者: 556556bt    時間: 2017-7-30 20:23




    Sure.... EA8500 is dual band AC2600 with MU-MIMO tech. to compare with the same extern, u need to take latest ubnt AP "UAP‑AC‑HD" as target which can serve 500+ wifi Users

---

作者: alanh999    時間: 2017-7-30 20:37




    I would say adding an additional AP is a better choice for #15.

Having MU-MIMO and additional 2.4GHZ and 5GHz channels won't help overcoming signal blockage of 2 solid walls.

    relocation of the Wi-Fi router may give u a better improvement.

我自己用過好多好多AP

我屋企眼鏡房,但兩間房既牆都係主力牆,成尺厚..用過呢到N咁多隻推介 LINKSYS NETGEAR DRAYTAK ASUS 乜野最TOP MODEL都玩哂.. 都係會係房有死位 最後換左UBNT之後先有一個點收得唔穩定.其他地方都收爆哂.. 所以我好滿意

P.S. 而家我仲要加多個WALL MOUNT版係房.連果個收我唔穩定個點都無埋...


我裝修前已經用呢隻AP. 當時係打橫放係櫃. 係隻AP 背面既位係收得差過正面(TEST上) 使用上都係3格同4格既分別.. 用到穩定就算

    而家我用緊既係AP-AC-LR

有D後悔應該買PRO..個POE PASSIVE 24V有D煩...
攪到我而家焗買佢個SW-8-150W 貴好多

作者: 556556bt    時間: 2017-7-31 12:47




    CHING 你個post 我都有睇過. 記得你話用塊亞膠歷膠片mount 住. 方便第時拆出黎換唔洗又要鑽過晒.

想問另一舊係乜黎?

---

作者: 556556bt    時間: 2017-7-31 12:49




    其實穩定係緊要過信號強弱. ....
收到但時強時弱, 就不是斷下斷下仲大劑.

---

作者: alanh999    時間: 2017-7-31 12:57



Some said LR performs better in environments with heavy interference and obstacles.
PRO can handle more clients simultaneously and deliver faster throughput but it may not perform as good as LR in difficult environments.

Lack of standard PoE support is a big shortfall of LR......

    你呢隻係long range wor. 會唔會係咁先收得咁好?

唔排除係咁.. 收得好就得喇~

如果只係得一隻LR可用ER-X當switch來推，都係24V passive PoE. 平好多。 當然最平係用Injector。

This kind of AP can give better reception one reason is it normally they mount on the ceiling. So more direct signal can reach the receiver side. I strongly suggest any ching who is considering get a new router because of poor wifi signal first try move their gear around their house.  See if any sweet spot there.

睇圖可能易明D.  簡單D 講係同一時間可以serve 多個users. 分開幾組天線同接收.

以前既AP 係分開timeslot 唔同時段係serve multiple users. 變常速度可以快左. 同埋唔會受到一D 慢client 影響.

---

作者: 556556bt    時間: 2017-7-31 16:04




    但D high end 家用router 走晒去出MU-MIMO AC2600 呢...

其實大部份AC Client 都係雙天線或以下.. 如果家居主打係部IPHONE .. 單春都得了...
根本係side 錢買多天線.

其實套裝唔係差太遠.. 若果唔係要勁多AP, 搞POE switch.. 買散既好似好D . 個injector 都值錢.

係，Control Philips light bulb only，個Hue hub本身冇sensor，只負責connect及control light bulb，但你自己可以寫app透過Hue controller control堆light bulb，包括GeoFencing, timer, color, auto on/off, light bulb grouping, etc...
